To all whom it may. concern:

Be it known that T, Gnonon HOLLAND, a citizen of the United States, residing atILa conia, in the county of Bellmap and State of New Hampshire, have invented certain new and useful Improvements in Puzzles, of which the following is a specification.

This invention relates to puzzles and particularly to numerical puzzles.

The primary object of the invention is to provide a puzzle which shall prove diflicult V to solve without knowing the proper combinations, and yet which will prove interesting and instructive to those attempting to discover the proper solution.

The invention consists generally in the arrangement of a plurality of members in septhat the sum total of the numbers in each row when added in one direction will be equal, while the sum of the difference between the numbers of the said rows will be equal to the sum of each row. With these objects in view together with others which will appear as the description proceeds, the invention resides in the novel formation, combination and arrangement of parts all as will be described more fully hereinafter illustrated in the drawings, and particularly pointed out in the claim.

In the drawing:

Figure 1 is a plan view illustrating the used in carrying out the invention,

Fig. 2 is a sectional View taken substantially on line 22 of Fig. 1,

Fig. 3 is a plan view illustrating certain of the blocks removed from the container, and arranged so as to show the solution of the puzzle, and

Fig. 4 is a plan view of certain of the blocks which are not essential in solving the puzzle.

Referring now to a suitable container, the same being in the form of a box of shallow depth as shown,

and which box is closed by a lid or cover 6.

Arranged within this box or container are a plurality of blocks indicated generally at 7, and which blocks bear certain indicia. Certain of the blocks bear the plus mark and others are provided with the mark of equality, while the remaining blocks are provided with numbers. Three of the blocks bear the number 45, while the remaining blocks bear numbers of lesser Value. The

blocks are numbered so that two rows of ten blocks each. may be provided, the numbers in each row being 1?, 2', 3, 4, 5, 6, 7, 8, 9 and; 0: While certain other of the blocks are numbered so as to provide a row often blocks numbering O, 2, 4, 6, 9, 1, 3, 5, 6 and 9; The remaining blocks in the container may be provided with any suitable numbers, these blocks being illustrated in Fig. 4 of the drawing, and are merely included in the set to make the puzzle more con using.

The end to be attained with the puzzle apparatus is, how can the number be subtracted from itself and still leave 45? To accomplish such a result, which seems impossible, the blocks bearing their numbers are arranged in the order shown in Fig. 3 of the drawing. The first row of blocks is arranged with the numbers 1 to O consecutively with the plus blocks arranged between the numbered blocks. At the end of the row an equality block is placed, and beyond the equality block is positioned one of the blocks bearing the number 45. In other words, the sum total of the numbersin this row equals 45. Directly below this row of blocks is positioned another row, the numbers of the second row being in inverse order. At the end of this second row is placed one of the sum total 45 blocks. It will be observed, also, that the plus blocks are inserted between the numbers of the second row and the digits of the second row are disposed directly be neath the digits of the first row. A third row of blocks is disposed beneath the second row, and these blocks are arranged in order as follows: 0,2,4, 6, 9, 1, 3, 5, 6, 9, at the end of which row is placed an equality mark and a block bearing the number 45. This third row also includes the various plus blocks between the various numbers in the said row. If desired, a strip 8 may be inserted between the second and third rows, so as to readily distinguish the same.

By adding the numbersin all three of the rows respectively, it will be observed greater or less numbers upon the blocks of the third row is equal to 45, or the sums of the added numbers in the first and second rows.

It is obvious that a puzzle of this character will prove very confusing, but will be entertaining and instructive. The sum total of 45 has been used in the present instance, but it is to be understood that a number of blocks, not shown in the drawing, may be used if desired, and it will also be understood that numbers of greater or less value may be employed.

l/Vhat is claimed is:

A puzzle device comprising two sets of blocks, the blocks of each set being num- Goplos 0! this patent may be obtained for five cents each, by addressing the Washington, I). 63."

bered 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 respectively, a third set of blocks numbered 1, 2, 3, 4c, 5, 6, 7, 9, 0, a block bearing the number &5 for each of said sets, blocks havingthe plus symbol thereon for each of said sets and being adapted to be placed between the consecutively numbered blocks therein, and a block for each set having "the mark of equality thereon, substantially as described.

In testimony whereof I alfix my signature in presence of two witnesses.
